UN-truth has some pictures of the crowds at Masjid al-Aqsa on Friday night, and also some pictures from the Qalandia checkpoint earlier that day.
She was wondering how so many people managed to get there despite all the checkpoints. Plenty of people who wanted to go, didn't make it. A friend of my son's from university tried to get into Jerusalem for Jummah and Taraweeh, but he is young and has a West Bank ID, so he tried to sneak through. He got caught, held for a few hours and roughed up a little. Then the forced him to sign a paper, ostensibly to promise he won't try it again, and then released.
